Summary Background Since December, 2019, Wuhan, China, has experienced an outbreak of coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Epidemiological and clinical characteristics of patients with COVID-19 have been reported but risk factors for mortality and a detailed clinical course of illness, including viral shedding, have not been well described. Methods In this retrospective, multicentre cohort study, we included all adult inpatients (≥18 years old) with laboratory-confirmed COVID-19 from Jinyintan Hospital and Wuhan Pulmonary Hospital (Wuhan, China) who had been discharged or had died by Jan 31, 2020. Demographic, clinical, treatment, and laboratory data, including serial samples for viral RNA detection, were extracted from electronic medical records and compared between survivors and non-survivors. We used univariable and multivariable logistic regression methods to explore the risk factors associated with in-hospital death. Findings 191 patients (135 from Jinyintan Hospital and 56 from Wuhan Pulmonary Hospital) were included in this study, of whom 137 were discharged and 54 died in hospital. 91 (48%) patients had a comorbidity, with hypertension being the most common (58 [30%] patients), followed by diabetes (36 [19%] patients) and coronary heart disease (15 [8%] patients). Multivariable regression showed increasing odds of in-hospital death associated with older age (odds ratio 1·10, 95% CI 1·03–1·17, per year increase; p=0·0043), higher Sequential Organ Failure Assessment (SOFA) score (5·65, 2·61–12·23; p Interpretation The potential risk factors of older age, high SOFA score, and d-dimer greater than 1 μg/mL could help clinicians to identify patients with poor prognosis at an early stage. Prolonged viral shedding provides the rationale for a strategy of isolation of infected patients and optimal antiviral interventions in the future.

Clinical course and risk factors for mortality of adult inpatients with COVID-19 in Wuhan, China: a retrospective cohort study

The purpose of this study is to analyze changes in the intestinal microflora of patients with COVID-19 in foreign countries and the role of microorganisms in the development of dysbacteriosis. Patients with Covid-19 usually complain of fever, cough, expectoration, shortness of breath, headache, and fatigue, but at the same time, some patients with Covid-19 experience gastrointestinal symptoms such as diarrhea, anorexia, nausea, and vomiting, complaints from the gastrointestinal trac. The literature review analyzed the etiological causes of intestinal dysbacteriosis in COVID-19. It has been established that in the intestinal microflora of patients with COVID-19, there is an increase in the number of opportunistic and pathogenic bacteria and a decrease in the number of beneficial microorganisms.

Characteristics of intestinal microbiotsenosis in covid-19 patients

Coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) induced a worldwide pandemic. The main clinical manifestations of COVID-19 patients have been fever, cough, dyspnea, and other respiratory symptoms. However, some patients’ initial symptoms have been nausea, vomiting, diarrhea and other gastrointestinal symptoms, and SARS-CoV-2 RNA could be found in their stool samples. Studies have shown that the gastrointestinal tract highly-expressed angiotensin-converting enzyme 2 is used by SARS-CoV-2 to enter cells. Therefore, exploring the damage caused by SARS-CoV-2 to the gastrointestinal tract and whether it could replicate in the gastrointestinal tract and transmit through fecal-oral route has significance for the diagnosis, treatment and prevention of COVID-19. We combined the current clinical data about COVID-19 patients with gastrointestinal symptoms as well as its pathogenic mechanism and prevention methods herein to review the relationship between the disease and gastrointestinal symptoms.
